Prescor PRV pressure reducing and safety valve PN25 1.0-6.0 bar R3/4"​ 27461

Pressure reducing and safety valve Prescor PRV is a reliable component of the installation, ensuring constant water pressure in the system. This is particularly important in installations supplying devices sensitive to pressure fluctuations, such as heating boilers or irrigation systems. Made of dezincification resistant brass (DZR), it guarantees long-lasting and trouble-free operation, even in harsh conditions.

Design and application

This valve, with a nominal diameter of DN20 and a threaded connection of R3/4", is designed to work with liquids. Its pressure adjustment range is from 1.0 to 6.0 bar, and the factory set pre-pressure is 3 bar. The pressure class PN25 indicates its strength and ability to operate in installations with a maximum working pressure of 25 bar. It will be useful wherever precise water pressure control is required – both in domestic and industrial installations. It is worth adding that this valve copes well with a water and glycol mixture up to a concentration of 50%, which expands its application.

Advantages and product features

• Durable DZR brass: the housing made of dezincification resistant brass provides high corrosion resistance and longevity. This translates to less frequent replacements and lower operating costs.
• Precise adjustment: the pressure adjustment range from 1 to 6 bar allows for accurate adaptation to the needs of a specific installation.
• Safety: the pressure reducing and safety valve protects the installation from excessive pressure, preventing damage to equipment and potential failures.
• Versatility: suitable for working with liquids and a mixture of water and glycol (up to 50%), which increases its application flexibility.
• Standard connection: R3/4" thread facilitates installation and integration with the existing installation.
• Compact dimensions: height 149 mm and length 160 mm allow for installation in a limited space. Working length is 130 mm.
• Thermal resistance: the maximum medium temperature is 80°C, allowing the valve to be used in various temperature conditions.

The Prescor PRV valve is a solid solution for every plumber or end-user looking for a reliable protection of the water installation against excessive pressure. Its design and materials of manufacture guarantee long-lasting and trouble-free operation.
